500 VA Single Phase Domestic Automatic Voltage Stabilizer

500 VA single phase AC automatic voltage stabilizer is based on relay control system & programmed control computerized technology for domestic purpose. It has many unique features which enable it to give high performance, better reliability and save electricity.

In this video ATO uses a voltage regulator and multimeter to test the output voltage of the 3 kva voltage stabilizer which has 140V to 270V AC input, 220V AC output. After testing, we may see that the output voltage is within 220V ± 6%, which is in line with the standard.
